That almost looks like an undead zombie version of MJ there. Yikes. The quality is more or less beyond repair. At best, some of it can be cleaned up a tiny bit.
This is also very clearly a multi-generational copy of a VHS tape, done on poor grade consumer VCRs. I'd have to say this is at least 5 times removed from the first master tape.
There have also been digital artifacts added on top of it, namely the blocks. Chroma noise was also not pre-filtered, so you have messy red/blue tints in shadows and elsewhere, moving about in the video.
The overscan can be masked out. If you don't know what that means, then read the sticky about
video noise at the edge of converted tapes, and how to fix it:

What kind of AVI is it? Lossless
HuffYUV, uncompressed AVI, something compressed like XVID/Divx?
The chroma/color, luma and IRE all appear to be severely damaged in the image. A difficult repair, with only minimal results possible.
